Pavement Crack and Joint Sealants
Abstract
The sealing or resealing of joints and cracks in both portland cement concrete (PCC) and bituminous pavements is a reoccurring maintenance problem for most military installations. The frequency of required resealing projects is dependent upon the sealing procedures used to install the original sealant, the condition of the pavement, type of sealant used, the amount and type of traffic on the pavement, and the climate to which the sealant is exposed. Joint sealants are used to minimize water seepage through pavement joints or cracks into water susceptible subbase or subgrade soils and to prevent joints or cracks from collecting incompressibles. Water seepage into the subbase or subgrade soils can cause a weakening of the pavement structure which can be seen by a pumping action of the pavement. Neglecting to maintain pavement joints and cracks can result in premature pavement failures, in turn leading to higher maintenance costs and higher pavement life-cycle costs. Keywords: Cold-applied joint sealants, Pavements, Field molded joint sealants, Hot-poured joint sealants.
